Bingham parameters of mortar

Mortar flow is usually measured using a drop table. We also measure minislump flow for high-fluidity mortar even though it is not regulated in a standard test method. The channel flow is a good alternative to sensitively estimate the Bingham parameters of a sample.

Bingham parameters of concrete

Slump and slump flow of concrete are requisitely measured. A rheological model easily converts the test results into the material properties: Bingham parameters, yield stress and plastic viscosity.
